### What problem does this PR solve?
Issue Number: None
External table metadata created by older versions may not contain a remote
table name. Although `getRemoteName()` falls back to the local table name, the
persisted field remains null after deserialization. Metadata paths that read
the stored state directly can therefore send a null table name to a remote
system, which may turn a table-scoped metadata lookup into a database-wide
lookup.
### How was it fixed?
Materialize the effective remote table name during Gson post-processing.
Explicit remote-name mappings remain unchanged, while older metadata that
omitted the field stores the existing local-name fallback.
### Release note
Fix external table metadata loading when old persisted metadata is missing
the remote table name.
### Check List (For Author)
- Test
- [x] Unit Test
- Behavior changed:
- [x] No. This materializes the fallback already defined by
`getRemoteName()`.
- Does this need documentation?
- [x] No.
